I will also comment that it sounds like copperkid has a strong math background, certainly strong enough for the course my kid took. Also, for those posting here who are not familiar with boarding schools, they administer tests the summer before entry to ensure students are placed in appropriate level courses, and they use the first few weeks of school to make any necessary adjustments. Sounds to me like the teacher is the issue. The student’s advisor will help resolve this problem.
Good luck, @copperboom, to you and your daughter. I’m sure the adults in her chain of command will find a good solution for her. Parenting from afar IS hard. Hugs.
